BUT when it came to describing the history and culture of Western civilization he readily acknowledged “a Judeo-Hellenistic-Christian tradition”:
“As a matter of fact, our Western heritage was shaped by a combination of three factors, the classical, Judaic, and Christian, and we could
readily speak of a Judeo-Hellenistic-Christian tradition within the framework of our Western civilization.”
So do two hyphens help? The term "hellenistic" does allow for a little breathing room between faiths, and it even gives an opening to "secular humanists" and "atheists"
